A system combining photovoltaic power generation and cogeneration is proposed to improve the photoelectric absorption capacity. First, a time-of-use price strategy is adopted to guide users to change their electricity consumption habits for participation in the demand response, and a demand response model is established. Then, particle swarm optimization (PSO) is used with the aim of minimizing the operation cost of the microgrid to achieve economic dispatching of the microgrid. This considers power balance equation constraints, unit operation constraints, energy storage constraints, and heat storage constraints. Finally, the simulation results show the improved level of photoelectric consumption using the proposed scheme and the economic benefits of the microgrid.

考虑热电联产和需求响应的微电网经济优化调度策略

为了提高光电吸收能力，提出了一种将光伏发电与热电联产的系统。首先，采用分时电价策略指导用户改变用电习惯，参与需求响应，建立需求响应模型。然后，以最小化微电网的运行成本为目的，使用粒子群优化（PSO）来实现微电网的经济调度。这考虑了功率平衡方程约束，单元运行约束，能量存储约束和储热约束。最后，仿真结果表明，所提出的方案提高了光电消耗水平，并具有微电网的经济效益。
